This .invention relates to rubbing-wheel type lighters.

.Theobjectof .the invention is to provide-.arubhing-wheel type. 'lighter, comprising a slide which may abe moved ain .twodifierent directions and apart from its .safety function is (effective at the same time as a .powertransmitting .means directlyiactuating the .drive of @the rubbing wheel and of :the lighter .lid, 01113750118 such slide thus being required to move a drive, which works, e. g.,.- underthe influence of a tippingspring, to either end .position (open-or closed) .of the lighten as required.

Rubbing-wheel type lighters are. known, which can be actuated: by means of a trigger, push slide, or the like alone, which can be moved in two different directions. :It *has not been-possible, however,.-.to apply such a device to otherithan the soscalled spring-lid .typelighters, in which the trigger serves. exclusively as'a safety lockagainst unintentional flying. open of l the lighter lid, which is preloaded ;by :aspring, .the trigger having .no other influence whatever on :the drive mechanism of .the. lighter. *For thatreasonsuch lighters show .all :the 'known drawbacks. of spring-lid type hters, .e.-.g., .thenecessity .of manually .closing the ;lid, which becomes .hotand sooty.

The accompanying drawings show :by way of examplean embodiment of. the'invention:

The rubbing-wheel type lighterconsistsasusual of a lighter casing 1, containing the fueli-tank v2, the wick 6 carried :bya wick carrier l, and the guiding device for the ignition stone 3, .which :is pressedby aspringA against the rubbing 1wheeli5.

In. order to rolfien, .and thereby .to ignite, 213118 closed :lighter.'(Fig. 1.), the slide lfijsifirstmoved downward-in.- the direction ofsthaarrow :41, against the force .of :the .spring .10, ..suitab1y with :.the thumbmf the hand :which .holds the lightens-so that the two:noses .lfirand .lz'l are ,placedside by side.

To permit the;deflection of.=the toothed segment .11 iwithoutchindrance, the slide 1. 8 .mustbemoized. downwardbeforabeing pressed inward, because: as ;is; also .shown :iniFig. :2, .the nose L4 lon. the':t0othed segment-can swing-.treely into the recess ibetween qthe noses 126, [:1 .only when theslidejsin; operating position (indicated by dashed lines).

Wh n-thelighter:isopen. the slide 5&8, isreleasedand.hywirtue ofthezspring 2B and of .the reselling-rod 139 1 automaticallymeturns to its upper initial position (indicated by solid lines in Fig. 2), so that the nose I on the toothed segment is now opposite the slide-nose 16. When the lighter lid 9 is now to be closed, after the lighter has been used, it is necessary only to again press the trigger l8 temporarily in the direction of the arrow 1) into the casing l to cause the clockwise re-deflection of the toothed segment I l by virtue of the tipping spring [3, whereupon all parts are again in the positions shown in Fig. 1.

In order to make the actuation of the lighter dependent on two movements of the slide of different direction, the slide, instead of bein longitudinally movable on the elastic slide rod l9, can also be rotatably mounted on said rod, as shown in Fig. 3. In this case the slide may have the form, e. g., of a cylindrical roller 26, whose part protruding out of the casing may be roughened or rippled (25) in order to facilitate the rotation of the roller 26. On the roller 26, the noses l6 and ll of the slide, which serve to deflect the toothed segment in one sense or the other, respectively, are not only displaced by height, but also at an angle apart, so that when the slide-nose l 6 co-operates with the nose !5 coordinated with it on the toothed segment, the other slide-nose is turned out of the plane of its nose I4 on the toothed segment, and vice versa.

When the lighter is closed, the slide 26 has relative to the toothed segment the position shown in Fig. 3. Since in this position the slidenose I! is placed outside of (inthe drawing: behind) the plane of the toothed segment ll, whereas the nose M on the toothed segment is deflected downward with the toothed segment, the nose I4 is not in the range of its slide-nose [6. Thus the lighter cannot be operated by mere pressure on the slide 26. To actuate the lighter, it is necessary to turn the slide 26 forward in a counterclockwise sense, against the force of the spring (not shown in the drawing) which holds it in its initial position, and thus to move the slide-nose l'l into its operating position, in which it lies opposite the nose 15 on the toothed segment, whereas at the same time the slide nose I6 is moved out of the plane of the toothed se ment. As soon as the toothed segment has been deflected by pressure on the rippled part 25 of the slide 26 into the position shown by dashed lines, and the wick been ignited thereby, the slide 26 is released and by virtue of the return spring automatically returns to its original position. To close the lighter, it is only necessary to press the slide 26, especially because the nose M on the toothed segment is now in the range of the slide-nose Hi.
